             ### 本次更新
 
             - **高级设置**：原「子代理设置」升级为「高级设置」，聚合子代理模型指定、实验功能开关与 WebUI 快捷入口
-            - **Kimi Code WebUI 应用内嵌窗口**：高级设置页可将新版 Web 界面以**独立顶层窗口**在应用内打开（单例、可缩放，关闭自动清理服务器进程），也可在系统浏览器打开（复用已运行的本地服务器）
+            - **仪表盘热力图双击弹窗**：双击热力图方块即可查看当日模型用量分布，每种模型展示 Token / 请求次数 / 费用 / 命中率
             - **子代理模型指定（实验功能）**：为子代理绑定次主力模型，不再默认继承主模型；实验开关改为滑动开关并修复开启态隐形
             - **兼容 kimi-code 0.33+（v2 引擎）**：`loop_control` 写入新键名 `max_attempts_per_step`，旧配置自动迁移并保留旧键兼容 `KIMI_CODE_LEGACY_FLAG=1`；hooks 候选补充新事件
             - models.dev 模型数据同步；官网企业版视觉升级；出品公司标识统一

+## v0.7.4
+
+### 仪表盘热力图双击弹窗（本次新增）
+
+- 热力图方块**双击**即可弹窗查看当日模型用量分布
+- 每种模型独立展示：**Token 用量 / 请求次数 / 费用 / 缓存命中率**（此前仅有 token 数）
+- 范围外日期（不在当前 7d / 30d / all 范围内的方块）不可双击、无放大效果
+- 弹窗内 Escape / 点击遮罩 / 关闭按钮均可关闭
+
+### 数据结构升级
+
+- 后端 `[dashboard] by_model` 从纯 token 数升级为结构化对象（含 requests / cost / cacheHitRate），弹窗和柱状图双击均展示全量指标
+
+### Downloads by platform
+
+- **Windows**: `.msi` installer
+- **macOS**: `.dmg` + `.app`（未签名，仅 Apple Silicon / M 系列芯片）
+- **Linux**: `.deb` / `.AppImage` / `.rpm`
+
+### macOS 安装说明（无开发者账号签名，需一次手动绕过）
+
+1. 下载 `Kimi.Switch_*.dmg`，双击挂载后把 `Kimi Switch.app` 拖入「应用程序」文件夹
+2. 下载本 Release 附带的 `install-macos.sh`，在终端运行：
+
+   ```bash
+   bash install-macos.sh
+   ```
+
+   脚本会自动清除下载隔离属性并启动应用，只需执行一次，之后正常使用。
+3. 手动替代方案：右键 `Kimi Switch.app` → 打开 → 弹窗点「打开」；或 系统设置 → 隐私与安全性 → 仍要打开
